Abstract

In an electrically actuatable fuel-injection valve for internal combustion engines, a piezoelectric oscillator (radial oscillator 11) which is provided with electrodes has at least one fuel-receiving chamber (12). The chamber (12) is in communication with the fuel feed path (constant-volume chamber 20) and an ejection opening (bore 17). The oscillator (11) is mounted in a block (18) out of which the fuel feed path (constant-volume chamber 20) is also formed. Furthermore, a high-voltage generator (35) is located, electrically shielded from the outside, within the block (18), which consists of metal. The high-voltage generator is connected to the electrodes of the piezoelectric oscillator (11) via feed lines (14, 15) which are conducted within the block (18).
